Glaucoma is a group of eye conditions that damage the optic nerve, usually due to high pressure in the eye. While the damage is not usually reversible, a variety of things can be done to prevent ...
Immediate manifestations of caustic substance ingestions include erosions of mucosal surfaces of the gastrointestinal tract or airway (which can cause bleeding if the erosions extend to a blood vessel), mouth and tongue swelling, drooling or hypersalivation, nausea, vomiting, dyspnea, dysphonia/aphonia, irritation of the eyes and skin.
A 2016 analysis of emergency department visits from 2010 to 2013 reported over 36,000 visits annually for chemical burns to the eye, with a median age at presentation of 32 years. [4] By individual year of age, 1- and 2-year-old children have the highest incidence of these injuries, with rates approximately 50% higher than the highest-risk ...
Sodium hydroxide is a dangerous chemical due to its ability to hydrolyze protein. If a dilute solution is spilled on the skin, burns may result if the area is not washed thoroughly and for several minutes with running water. Splashes in the eye can be more serious and can lead to blindness. [40]
Long-term use of PMMA or thick hydrogel contact lenses have been found to cause increased eye irritability, photophobia, blurred vision, and persistent haloes. [18] There is some evidence to show that rigid gas permeable contact lenses are capable of slowing myopic progression after long-term wear. This same effect was not found in patients who ...
Vision loss in toxic and nutritional optic neuropathy is bilateral, symmetric, painless, gradual, and progressive. Dyschromatopsia, a change in color vision, is often the first symptom. Some patients notice that certain colors, particularly red, are less bright or vivid; others have a general loss of color perception.
The prognosis for CSR is generally excellent. While immediate vision loss may be as poor as 20/200 in the affected eye, clinically, over 90% of patients regain 20/25 vision or better within 45 days. [1] Once the fluid has resolved, either spontaneously or through treatment, distortion is reduced and visual acuity improves as the eye heals.
